Title: Air flap with two weights for preventing an afterflow of fresh air through the fire space into the chimney, with the burner cut out, for installation in the exhaust-gas or air-intake conduit of oil-fired and gas-fired fireplaces
Inventor: EPPINGER OTTO
IPC: F23L3/00
Filed: 1981-02-09
Abstract: In oil-heating systems in particular, when the burner is stopped fresh air flows, as a result of the chimney draught, through the fire space of a heating boiler and thereby cools the latter. In order to improve the efficiency of the heating system, it is proposed, by means of the air flap according to the invention, to shut off the exhaust-gas conduit or air-intake conduit when the burner is stopped. The air flap is articulated on a horizontal axle and is installed in such a way that it is opened by the generated burner pressure or intake pressure and is closed by a counterweight when the burner is stopped. The counterweight consists of two weights (7, 7a) adjustable relative to one another. These two weights make possible an improved adaptation and adjustment to different heating systems having different burner capacities and chimney draughts. For this purpose, the weight (7a) is set vertically, with the flap closed, so that the flap can be adjusted solely as a result of the effect of the weight (7) in such a way that it closes sealingly against the chimney draught. <IMAGE>

Patent DE-3113441-A1 (DE)
Title: Support device
Inventor: STOCZEK HANS JOACHIM
IPC: A47B57/54
Filed: 1981-04-03
Abstract: On a support device, consisting of an angle rail, in particular on a profiled bar consisting of a plurality of angle rails and a support element fitted thereto, the object is to be achieved of providing a support device which is not to be attached in the grooves of the profiled bars, but which is to be attached to the angle rails themselves. The invention achieves this object due to the fact that at least one recess is arranged in each case on both outer sides of the angle rail, and that the edge or projections on the edge of a support element engage in said recess. In this manner it is possible to attach further support elements, which can support shelves in showcases, for example, on profiled bars whose grooves are filled out between the angle rails due to accommodating edges of panels.

Title: Filter for aquariums
Inventor: EHEIM GUNTHER
IPC: F04D13/06
Filed: 1981-09-14
Abstract: A filter for aquariums containing a filter cartridge and an adjoining head is proposed, which contains in its casing a self-starting synchronous motor with a permanent-magnet rotor and a pump impeller which sits directly on the rotor shaft in a pump chamber whose radial outlet, located on a perimeter side, is situated at the bottom end of the head and opens into a discharge duct leading to the top end of the head. The rotor shaft is provided with a continuous bearing bore and is supported, on a divided shaft formed by two shaft pins, in a precisely fitting manner, but with free running clearance. Each shaft pin is seated, at its end, in an elastic rubber socket. The rotor shaft consists of a carbon material, the shaft pins of a ceramic material. Both parts are expediently run in together and ensure good centring and a substantially true-running bearing arrangement. The pump impeller having rigid radial vanes is clipped onto the rotor shaft axially in a detachable manner. Relative to the rotor shaft, it is freely rotatable by a substantial circumferential angle and has radial damping end stops, against which a fixed radial end stop of the rotor shaft strikes for the purpose of rotational locking (slaving) in the drive direction. The bush, which accommodates the entire rotor and adjoins the pump chamber axially, is open at both ends to form a lubricating and cooling duct which runs between the bush and the rotor and is connected, near the head, to a pressure relief port via a small radial duct. Between the bottom plate and the pump chamber there is a control disc, which can be rotationally adjusted manually, for controlling the throughput. Said control disc has an axially continuous control window with a radial duct adjoining it which is covered axially by the bottom plate and towards the centre communicates with the axial suction side of the pump, depending on the rotational position of the control disc, via coincident wall openings in the pipe section of the control disc and bottom-plate pipe stubs engaging these.

Title: Clutch disc with torsional vibration damper and spring system in the form of pins
Inventor: ANDERS PETER DIPL ING
IPC: F16F15/123
Filed: 1981-10-06
Abstract: The invention relates to a clutch disc with a torsional vibration damper, in which helical springs are provided as spring elements. At the ends, these helical springs are supported against corresponding edges of apertures both in the cover plates and in the hub disc. According to the present invention, however, in at least one direction of loading the helical springs are not supported via these apertures but via pins, the longitudinal axes of which extend parallel to the axis of rotation of the clutch disc and the longitudinal axes of which intersect the longitudinal axes of the helical springs or are at only a short distance from the latter. As a result, the helical springs can align themselves in any loading position in such a way that the end faces of the springs are aligned parallel to one another. The arrangement of these pins is particularly clear from Fig. 2, the pins being secured and fixed axially by correspondingly arched regions of the cover plates. <IMAGE>
